Molly Sims shares excited pregnancy update

Model on Motherhood: "I Can't Wait!"

The expecting model and Project Accessory host continues to document her pregnancy progress in a Bump Watch photo album on her website.

It's been just over a month since model Molly Sims found out that she and husband Scott Stuber are expecting their first child. She has invited fans to follow her pregnancy updates on her website, including today's update — she's now five months along!

"It's hard for even me to believe, but as of last week I'm officially five months pregnant," she posted on MollySims.com. "The baby just started kicking and at this point it's only a matter of weeks until life as I know it is going to completely change — and I can't wait!"

The Project Accessory reality show host started documenting her pregnancy progress with photo uploads last month. "I thought it would be fun to document my baby bump on the site each month, starting today," she first announced at four months pregnant. "That way all of you can see how far along I am, and I'll have all of the pictures to look back on once the little bun in the oven arrives."

And the soon-to-be parent is already reaping the rewards of her virtual scrapbook. "It's crazy to see the difference from just a month ago, isn't it?" she wrote earlier this morning.

Their honeymoon baby is due this June. "A first pregnancy is a nerve-wracking experience of course, but mostly we are just thrilled and excited," Sims said when announcing the pregnancy. "We can't wait to meet him or her."
